chroot is a system call that causes all descended processes to treat a
directory in the filesystem as the root directory (/). When you do
this to an interactive Bash shell, you then have the ability to launch
programs and do development work, etc. from this chroot.
Debian has good tools for doing this sort of thing--debootstrap and
friends can install a new system (etch, lenny, sid, and more) in a
folder for you, and you can even install an entire 32-bit userland on
a 64-bit system, which is useful for running 32-bit Firefox with stuff
like the non-free Adobe Flash plugin (FYI-if you're going to point out
nspluginwrapper, please also tell me how to make sound with PulseAudio
work in that setup). Then there are tools like schroot (apt-get
install schroot) which can be configured to launch programs from
inside the chroot in one command line, complete with 32-bit uname()
emulation if so desired.
